Abstract: Eusieus scutalis (A.-H.), is a common phytoseiid mite in Egypt. However, the present study aims to throw more light on the biology and life table parameters of E. scutalis which was reared under laboratory conditions of 26°C and 70% R.H., on palm pollen, immature stages of Tetranychus urticae koch andBemisia tabaci Genn. Life cycle averaged 5.20 and 6.19 days, 6.40 and 7.23 days, 7.30 and 7.85 days for male and female when fed on palm pollen, immature stages of T. urticae and B. tabaci, respectively. The highest R0 value of 17.88 expected female progeny per female was obtained with a diet of date palm and followed by 16.03 and 13.60 for T. urticae and B. tabaci, respectively. The intrinsic rate of natural increase (rm) and subsequently, the finite rate of increase (erm) averaged 0.232-1.26; 0.191-1.21 and 0.175-1.91 when E. scutalis was provided with date palm pollen, T. urticae and B. tabaci, respectively. Date palm pollen shortened the mean generation time and caused the highest rates of R0, rm and erm parameters followed by a diet of T. urticae. While B. tabaci proved to be the least favorite food source for E. scutalis.
